Aza-9-crown-3 is a cyclic polyether compound with the chemical formula C6H15NO3. It consists of a nine-membered ring containing three nitrogen atoms and six oxygen atoms, which gives it the ability to form stable complexes with metal ions. This property makes it useful in various applications, such as in the synthesis of metal complexes, as a chelating agent in analytical chemistry, and in the design of ion-selective electrodes. The compound's structure allows for selective binding of specific metal ions, which can be tailored by modifying the substituents on the nitrogen atoms. Aza-9-crown-3 is a versatile building block in supramolecular chemistry and has potential applications in drug delivery, catalysis, and molecular recognition.

7234-71-1 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 7234-71-1 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 7,2,3 and 4 respectively; the second part has 2 digits, 7 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 7234-71:
(6*7)+(5*2)+(4*3)+(3*4)+(2*7)+(1*1)=91
91 % 10 = 1
So 7234-71-1 is a valid CAS Registry Number.

Lipophilic Bis(monoaza crown ether) Derivatives: Synthesis and Cation-Complexing Properties

Sakamoto, Hidefumi,Kimura, Keiichi,Koseki, Yasuaki,Matsuo, Mitsunori,Shono, Toshiyuki

, p. 4974 - 4979 (2007/10/02)

Eleven lipophilic bis(monoaza crown ether) derivatives were synthesized, in which two monoaza crown ethers with 9-, 12-, 15-, or 18-membered rings are linked through the nitrogen atoms by an alkane-, diether-, or diester-type bridge chain bearing a dodecyl group.Sodium and potassium binding with the bis(monoaza crown ether) was determined potentiometrically and compared with those for previous bis(crown ethers) 5 (n = 1 - 3) and corresponding monocyclic analogues 4 and 6 (n = 1 - 3).Marked bis(crown ether) effect was observed only for the alkane-type bis(monoaza-12-crown-4) and bis(monoaza-15-crown-5) derivatives 1 (n = 1,2) on complexing Na+ and K+, respectively.It was suggested that in some of the other bis(monoaza crown ethers) lariat-ether effect works instead.Bis(monoaza-9-crown-3) derivatives 1 and 2 (n = 0) possess very poor cation-complexing ability.Acidity constant values gave some hints about the bis(crown ether) effect.
